1 Claim.

board 5 that is generally oblong and is preferably formed of lightmetal, such as steekbeing also preferably perforated as at B to furthermaterially reduce the weight thereof.

The board 6 is adapted to have placed thereon the arm of the patient andfor the forearm of the patient there is provided a rest I.

As shown, the rest I embodies a body member 8 that is raisedintermediate its ends, and adjacent one end as at 9 and has a gradualslope toward one end as at Ill and a more pronounced slope II in thedirection of the opposite end;

Among the objects of the present invention is to improve and simplifythe splint to the end that the same will be more efficient and easilyapplicable; the intent, object, and purpose of the invention being toprovide a splint of this character whereby intravenous infusions andtransfusions may be administered with efficiency, while a patient is inthe progress of being moved or transported from one location to another,as from one bed to another, or in an ambulance from one location toanother, such as from the home or street to the hospital.

The present invention, together with its many objects and advantageswill be appreciated from a study of the following description taken inconnection with the accompanying drawings wherein Figure 1 is aperspective view of an intravenous splint embodying the features of thepresent invention.

Figure 2 is a fragmentary bottom plan view illustrating certain detailshereinafter more fully referred to.

Figure '3 is a longitudinal sectional view through the splint.

Figure 4 is a transverse sectional view through the splint at the elbowclamp-equipped end portion thereof.

Figure 5 is a transverse sectional view through the splint andillustrating certain details hereinafter more fully referred to.

Figure 6 is a fragmentary sectional view through the body of the forearmrest illustrating a slightly modified form of the invention ashereinafter more fully referred to.

Figure 7 is a side elevational view of a modifled form of clamp andholder therefor.

' Figure 8 is a fragmentary perspective view of clamp holder hereinaftermore fully referred to.

Referring more in detail to the drawings, it will be seen that inaccordance with the invention, this form of splint embodies a main bodywith the top of the body 8 being somewhat concave in crosssection toconformably receive the forearm of the patient. a

Also secured to the topside of the body 8 of the rest is a pad orsurface covering i2 of rubber or other suitable soft and yieldingmaterial.

The rest 1 is secured at the desired positionof adjustmentlongitudinally of the base or board 5 through the medium of short studbolts it that screw-threadedly engage bosses H on the underside of therest body 8.

The bosses H are accommodated in a longitudinal slot it providedtherefor in the base or board 5 and coact therewith in restrainingshifting movement of the rest I in a direction longitudinally of thebase or board 5.

To assist in maintaining the forearm at the hand in position on the restI, the same has disposed transversely thereof a restraining strap l 8that at its opposite ends is provided with eyelets II to engage hooks i8that project from opposite sides of the body 8 of the rest I. The hooksl8 may be either of the shape shown in Figure l, or of the shapesuggested in Figure 6, and in which latter figure the hooks areindicated by the reference numeral I80.

The restraining strap I8 is characterized by the provision of a slot l9therein through which the thumb extends, and a buckle-equipped strapportion 20 that can be adjusted for contracting the strap I 8 across thehand as the size of the hand of the patient may require. To support thearm of the patient at the back of the elbow there is provided at the endof theboard 5 remote from the rest 1 a substantially wedge-shaped rest20. The rest 20 may be cemented or otherwise positively secured to theboard 5, and the board 5, in the region of the rest 20, is provided witha transverse slot, or opening 2 I, so that minimum resistance is offeredby the board to the rest 20, with the result that the full benefits ofthe resiliency of the rest will inure to the advantage of the patient,thus adding further to the comfortableness of the splint; the rest 23being preferably formed solely of sponge rubber, or some other similarresilient substance.

Also, in accordance with the present invention. there is provided anadjustable clamp, indicated generally by the reference numeral 22, forclamping the arm at the elbow.

The clamp 22 comprises a pair of substantially identical, opposed jaws23-23.

Each of the jaws 23 embodies a body part formedof some light metal,preferably aluminum, in the form of a plate curved transversely andhaving a marginal flange projecting therefrom at the convex side of theplate.

Upper and lower flanges are apertured to accommodate a retaining bolt 24that extends upwardly through the apertures in the flanges and alsothrough a transverse slot 23 in the board or base member 3 to secure theassociated jaw at the desired position in a direction transversely'ofthe plate or base member 5.

The confronting concave faces of the clamp members are covered withsheets 28 of sponge rubber, or other suitable resilient material.

To retain the arm, at the elbow, clamped between the jaws 23 of theclamp 22, and against being pulled upwardly from between the jaws, thespace between said jaws 23, adjacent one end of the clamp, is bridged bya restraining, adjustable strap 26.

'I'he strap 26, as shown to advantage in Figure 1, is trained throughsuitable loops 2! provided on the uppermost flanges of the jaw membersas shown.

From the description thus far, it will be seen that the arm rests on thebase member 5 with the forearm and hand supported by the rest I, theelbow secured between the jaws of the clamp 22, and the arm in back ofthe elbow supported or sustained by the rest 20. Thus the arm is held inposition to facilitate the giving of an intravenous infusion or a bloodtransfusion, as conditions may require.

Further, and to render the device more comfortable to the patient, thebase member 3, inwardly from the rest 20, is provided with an opening 28at a point where the elbow joint would be most likely to rest on themember 5.

Seated in the opening 28 is a cushion 23 serving as a rest for the elbowjoint.

Further in accordance with the present invention the base 5, adjacentone edge thereof, is pro- In lieu of the support 3 I, resort may be hadto a support of a flexible type and such as suggested in Figure 7 andindicated by the reference numeral 42.

The support 42 is in the form of a flexible standard, or post 43equipped at one end with a threaded stem 44 and nut and washer means 46through the medium of which, and the aforementioned slot 30, suchsupport 42 is secured to the base or board I at the desired positionlengthwise vided with a slot 30 elongated longitudinally thereof, andfor the purpose of facilitating the securing thereto of a support for asurgical needle, syringe clamp, or other surgical instrument that may bedesired.

In Figure 1, one such form of support is shown and indicated by thereference numeral 3 I.

The support 3| embodies a tubular standard 32 that atone end is providedwith a threaded pin or stud 33 that extends through the slot 30 and isequipped with a nut and washer assembly 34, and through the medium ofwhich the support 30 is secured at the desired position of adjustmentlengthwise of the board or base member 5.

Further, the support at embodies a vertically shiftable and adjustablerod 35 that has a threaded section telescoped by the standard 3|, and awing nut 36 threadedly engaged with the threaded section of the rod 35and adapted to be threaded home against the upper end of the standard 3|for securing the rod 35 at the desired position of vertical adjustment.

of said base or board.

At the upper, or free end thereof the standard 43 of support 42 haspivoted thereto, as at 48, the shank portion of a clamp indicatedgenerally by the reference numeral 41.

Clamp 41 is illustrated as being of a type particularly designed forengagement with a surgical needle of a type other than an intravenoussyringe, and. for example, as might be employed in giving a bloodtransfusion.

Other types of supports and clamps may be resorted to and, for example,a support such as hereinbefore referred to and indicated by thereference numeral 30, may be employed but in a modified form, as, forexample, instead of having the arm 31 of the rod 35 terminating in aslotted extension 38, said arm, as suggested in Figure 8 and indicatedby thereierence numeral 31a, may terminate at its free end in anupstanding integral shank 48 on which is sleeved a sleeve element 49equipped with a set screw 50 through the medium of which the sleeve 49is secured at the desired position of vertical adjustment on the shank48.

Also, as shown in Figure 8, the sleeve 43 has pivoted thereto a secondsleeve 5| through which is trained a carrier rod 52, and from which roda clamp or the like, or a syringe needle, or other surgical appliancemay be suspended.

Also, in accordance with the present invention. the board or base member5 has tapped into it, adjacent one corner thereof, a threaded opening 63to accommodate the threaded end of a suspension standard 64.

As shown the standard 54 is provided at its upper end with a laterallyextending ,-hook 55 from which various forms of surgical appliances maybe suspended for the convenience of the surgeon and his attendant.

Also in Figure-5 is suggested other uses of the standard 54.

As, for example, a heating pad, suggested by broken lines in Figure 5and indicated by the reference numeral 56, may be suitably secured onthe standard 54 as may also and if desired, associated with the heatingpad 56 a thermometer 51.

Also, in accordance with the present invention, the board or base 6,preferably at the end thereof equipped with the rest 20, is equippedwith an apertured lug 53 through which is trained a tourniquet tube 59.

Also, in accordance with the present invention, the board 5 at one edgethereof is provided with a notch 60 elongated longitudinally of theboard, and between the ends of the notch there is secured to the boardlongitudinally spaced rings or annular bracket members 60 to accommodatea battery-equipped case 6| Such a'battery-equipped case Bl will be foundadvantageous when using the device in an ambulance, or in the field toprovide a supply of electric current as may be needed. To that end thecase 8| is provided at one end thereof with an electrical receptacle forreceiving the plug on one end of an extension cord 62 as suggested inFigure 1, or the plug end of an electric cord 63 provided, for example,and as suggested in Figure 5, for the heating pad 56.

It will thus be seen that the splint may be readily equipped for almostany type of emer-'.

gency use, and may be equipped, in addition to what has been hereinsuggested, and as the use ,from the spirit of the invention as hereinillustrated, described, and claimed.

Having thus described the invention what is claimed as new is: it

In a surgical splint of the class described, a splint board provided atone end thereof with a stationary rest having an inclined surface tosupport the arm at the back of the elbow joint, a second rest mounted onthe board for longitudinal adjustment relative thereto and foraccommodating the forearm at the hand, a rest for the elbow joint on theboard'intermediate the firstnamed rest, and a clamp for engaging the armat the elbow embodying a pair of clamping jaws disposed on the board atvopposite sides of the rest for the elbow joint and adjustable towardsand away from one another transversely of the board, a restraining strapextending transversely of these-cond-named rest, and interengaging meanson the respective opposite ends of the strap, and on opposite sides ofthe second-named rest for detachably securing the ends of said,

strap to the rest, and the jaws of said clamp provided on the upperedges thereof with loops, and an adjustable restraining strap trainedthrough said loops and bridging the space between said clamping jaws;and said board adjacent one longitudinal edge thereof provided with aslot elongated longitudinally of the board to provide for the securingthereto a support for surgical appliances in a position of adjustmentlengthwise of the board.
